2 Claims.

Thi invention relates to improved fastenings for a combination stormsash and screen having separate upper and lower frames for both screenand storm window.

An important object of the invention includes the provision of an easilyattachable and removable storm sash or the like having a novel fastenertherefor so that the frame may be inserted from the interior of thebuilding and attached in a matter of seconds.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which:

Fig. 1 is a view in elevation from the exterior showing a storm sash anda window screen in position;

Fig. 2 is a vertical section through an installation with parts brokenaway;

Fig. 3 is a section through the permanent windown frame and theremovable sash;

Fig. 4 is a view in elevation of the parts of Fig. 3;

Fig. 5 is a detail view showing a finger hold;

Fig. 6 is a detail view of a ventilator in a storm sash; and

Fig. 7 is a detail view of a part of the fastener which is applied tothe permanent window frame.

In the drawing, the numeral l0 indicates the vertical stiles defining apermanently installed window frame and these stiles are connected asusual at the top by rail l2 and at the bottom by the windowsill l4.Parts l0, l2, and 14 are all permanent parts of the building.

A lower sash having side elements 16, a top element It, and a bottomelement 20 is provided, these elements holding either the screen 22 or apane of window glasss 24, by any desired or convenient means such asputty, or moulding 26. The side elements l6 are rabbeted as at 28 toclosely fit the inside corners of the stiles of the permanent windowframe. The bottom element 20 is beveled as at 30 to conform to thepermanent sill l4; and the top element I8 is provided with spacedrabbets, 32 at the outside aspect and 34 at the interior side thereof,these rabbets defining between them a tongue 36 which projects upwardlyfor a purpose to be described. The rabbet 32 is considerably lower thanthe interior rabbet 34 as will be seen in Fig. 2.

The upper sash comprises a pair of side elements 38 rabbeted at 40 inthe same manner as the lower sash side elements It. In the upper sashthe side elements 38 are connected by a top element 42 which is rabbetedat 44 to closely fit the inside edge of the permanent frame top elementl2, see Fig. 2. The side elements 38 are connected at the bottom by arail 46 which 15 grooved centrally thereof as at 48 to conform to therabbets 32 and 34 and tongue 36. Fingerholds 50 are provided wheredesired for a pur- Figs. 3 and 7, arranged to bear on the inner faces ofthe stiles l0, and each has at its rear edge an abutment flange 56 andbetween its front and rear edges is doubled or folded on itself to forma cam plate Or flange 62, said flanges 56 and 52 being bent in oppositedirections laterally from the body of the bracket plate. Each bracketplate is provided with spurs or points 58 for holding the sametemporarily in position on the inner face of the stile so thatafastener, such as a screw 60, maybe passed through the body of thebracket plate in advance of the flange 62 and into the stile to securethe bracket plate to the stile. When the bracket 55 is secured in placethe flange 5B bears against the inner face of the stile and the flange62 projects beyond the inner face of the stile into the window openingfor coaction with the associated pivoted latch on the sash side elementsor rails, the flange 5B gauging the position of the bracket plate sothat the flange 62 is disposed in proper working position. The flange62, as shown, is inclined downwardly and inwardly to the plane of thewindow frame to form a cam member. Hence when the bracket 55 is properlyapplied to the window frame, the cam projection 62 will be locatedautomatically in correct position for camming engagement with element 54of the pivoted latch and it will be seen that in the frictional holdingcondition of these latches, the handles 52 thereof will be disposedbehind the side elements of the sashes in an out of the way positionwhich is not visible from the exterior. It will -be understood that theflange 56 serves not only as a gauging element but also as a bracingelement to sustain the bracket 55 and prevent the same from shiftingforward under the pressure of the latch arm 54 against the cam flange 62in a latching action, by which the pressure will be relieved from thescrew 60 and said screw prevented from working loose,

The action of the latch arm 54 on the cam flange 62 obviously erves todraw the flange 28 of the sash tightly against the outer face of thestile l0. By offsetting the arm 54 of the pivoted latch inwardly fromthe plane of its handle the pivoted fastener may be mounted closelyagainst the sash rail, to avoid the use of a long pivot, while the arm54 projects inwardly for cooperation with cam flange 62. A ventilator 64of any desired construction may be used in the bottom element 20 of thestorm sash if desired.

In order to secure the sashes in position at the exterior of thepermanent window frame, it is necessary merely to pass the removablesash through the window frame from the interior to the exterior, itbeing preferred to put the bottom sash in position flrst so that itrests upon the sill I4. The finger-holds 50 are then used to hold thesash in position while the latches are rotated to secure the sash inposition. The upper sash is then passed through the window frame and setupon the upper member [8 so that the tongue and groove connection willfit, and then the fingar-holds are utilized to bring the upper sash intoclosely fitting position with the permanent window frame, the latchesthen being rotated as 'before to complete the installation.

It will be clear that this invention provides screen's or storm sashwhich are very easy to apply to the window and which can be applied andsecured completely from the inside of the building. Also, if desired, itis possible to have both of the removable sashes either storm window orscreen or any combination of the two desired, as shown in Fig. 1. Byusing two screen sashes, the permanent window may be opened at eithertop or bottom or both for improved ventilation in fair weather.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:

1. The combination with a window frame, and a sash having side railsformed with portions bearing against the outer faces of the stiles ofthe frame, of coacting pairs of fastening devices on the side rails andstiles operative to draw and hold the rails secured tightly against thestiles, each pair of fastening devices comprising a. fastening memberpivoted to a sash rail and having a latch arm, and a cooperatingfastening member embodying a bracket plate bearing against the innerface of a frame stile and secured at its front portion by fasteningmeans to the stile, said bracket plate having an abutment flange bearingagainst the rear face of the stile and a laterally projecting cam flangeinclined to the plane of the frame and arranged between the abutmentflange and said fastening means for engagement by the latch arm of thepivoted fastener on the sash rail to draw the rail against the stile,said abutment flange operating to brace the bracket plate against thepressure of the latch arm on the cam flange to relieve the fasteningmeans from excessive strain.

2. The combination with a winndow frame, and a sash having side railsformed with portions bearing against the outer faces of the stiles ofthe frame, of coacting pairs of fastening devices on the side rails andstiles operative to draw and hold the rails secured tightly against thestiles, each pair of fastening devices comprising a fastening memberpivoted to a sash rail in close proximity thereto and having anoperating handle and a latch arm projecting laterally therefrom andoffset to lie in rear thereof, and a cooperating fastening memberembodying a bracket plate bearing against the irmer face of a framestile and secured at itsfront portion by fastening means to thestile,.said bracket plate having an abutment flange bearing against therear face of the stile and a laterally projecting cam flange inclined tothe plane of the frame and arranged between the abutment flange and saidfastening means for engagement by the latch arm of the pivoted fasteneron the sash rail to draw the rail against the stile, said abutmentflange operating to brace the bracket plate against the pressure of thelatch arm on the cam flange to relieve the fastening means fromexcessive strain.
